Energy

Sensors are the eyes and ears of your control system and fundamental to its operation. Inaccurate measurements, due to faulty or poorly maintained sensors, can result in wasted energy, substandard crop performance and even increased disease so they are very important. In this technical update, we discuss what to watch out for when choosing and looking after sensors in glasshouses.

This is part one of a two part update, in which we revisit the conventional sources of CO2 supply and discuss the influence of factors, such as heat requirement and electricity price on the cost attributed to CO2 supply. Conventional sources includes: flue gas from the ‘back of the gas boiler’, LPG or kerosene direct-fired heaters, CHP units or pure CO2 delivered to site.

This is the second part of a two-part update on CO2. The first part covered the costs and characteristics of conventional CO2 supply. Here, we look at the supply of CO2 from biomass and anaerobic digestion and discuss how it has developed since the uptake of renewable-based heating systems.

The principles and benefits of diffuse light in greenhouse crops are widely accepted. In this document, we remind ourselves why diffuse light is important, explain how it is measured and the different solutions available to enable this benefit in your greenhouse.

Energy makes the world go round and it can manifest itself in many forms including radiation, light and chemical. However, we are mostly concerned with it as heat, electricity or as fuel (i.e. oil, gas, wood etc.) which, for the most part we pay for. It’s important that we are able to measure it, so we can evaluate and compare its costs and assess how efficiently it’s being used. Read more about how best to measure your energy use in this technical updates.

Screens have become an essential tool for energy saving, shading and climate control in modern protected horticulture. New screen materials which save more heat energy and transmit more light have been developed, enabling screens to be deployed more in the daytime, or in double layers. There has never been a wider range of screen materials to give the optimum balance between energy saving, light transmission and shading. Read more in this technical update.

Biomass heating has become more popular over recent years, but one disadvantage has been that biomass boiler flue gasses can't be used for CO2 enrichment without cleaning them. Read this technical update to read about developments in biomass flue gas cleaning systems.
